CONCRETE LAME STAND.

Application filed October 16,1926. SerialV No. 141,926.

My inventiony relates to concrete columns especially designed and adapted for supporting metallic casings for gas or electric lamps for municipal lighting. Such casings are, of course, exposed to the weather and the objection to concrete lamp stands of the v prior art isthat such casings inevitably cor rode,`particularly when exposed to salt air, and the concrete is stained by the rain water containingthe products of such corrosion. F or instance, if the lamp casing is formed of ferrie metal; the concrete is stained in streaks of dirty brown by the iron oxide carried by the -rain water flowing downward upon the outer surface of the column. Similarly, if the casingis formed of copper or brass, the rain water is stained green and correspondingly discolors the concrete.- If the casing is formed of, or coated witlnzinc, the products of its corrosion stain the columns a dirty white. Therefore, the object and effect of my invention is to provide a concrete column with means for preventing staining the exterior thereof with the products of corrosion of any metallic superstructure which it supports.

As hereinafter described, my invention includes a concrete column having, at the top thereof, a catch basin for liquid, including a depression, so proportioned and arranged that the products of corrosion from the lamp casing supported by said column pass into said basin instead of upon the exterior of said column, and said basin is provided with means to drain it, preferablyjncluding a pipe extending downwardly within the column, in association with other metallic reinforcing elements, and opening laterally from the column at the bottom thereof.

My invention includes the various novel features of construction and arrangement hereinafter more denitely specified.

In said drawing; I have shown a vertical sectional view of a column yembodying my invention, with a lamp casing mounted thereon; the latter being partly in elevation and partly in section.

In said drawing; the concrete column 1 may be of any suitable size and shape, but is preferably tapered from the top to the bottom thereof, as indicated, and cast upon an internal kmetallic reinforcing structure, including vertical rods 2 and transverse rings 3, 4, 5, and 6.

Said column has the catch basin 8 at th top thereof arranged to be drained through the port 9 which, preferably, leads to the pipe 10 which extends downwardly through said column 1, as part of the metallic' reinforcing structure thereof, and extends to the perimeter of the base of said column in registry with the discharge port 11 through which-any liquid caught in said basin 8 is discharged by gravity.

I'findvr it convenient to provide said concrete basin 8 with a metallic lining 12, preferably of Monel metal or other metal-capableof resisting corrosion. Said lining has the upwardly extending axial ytubular projection lll surrounding the concrete axial projection. 15; thus adapting said column to receive, ink detachable coaxial relation therewith, the lamp casing base 16 whichhas the conical socket member 17 arranged to fit and frictionally engage said conical tubular projection 14C on the column. Said lamp casing may inclose a source of light 19 of any character, for instance, a gas lamp of the mantle type.

However, it is to be understood that any other suitable means may be provided for connecting the column with the casing. For instance, said base socket 17 may be provided With an internal screw thread for engagement with said projection 14, or, said base may be made in unitary relation with the lining 12.`

Although I have described a form of my f invention particularly designed for supporting lamp casingsr; itis to be understood that it may be advantageously employed to support metallic traffic signs or any other superstructure capable of discoloring rain or other moisture gravit-,ating therefrom.

Therefore, VI do not desire to limit myself tothe precise details of construction and arrangement herein setv forth, as it is obvious that vvarious modifications may be made therein. without departing from the essential features of my invention, as defined in the appended claims.

I claim: 1. A lamp stand formed of concrete having a liquid catch rbasin at the top thereof, and an axial projection extending upwardly from the bottom of said basin, adapted to receive and support a lamp casing; and means arranged to drain said basin independently of the exterior surface of said column.

2. A lamp stand formed of concrete having liquid catch basin at the top thereof,

and an axial projection extending upwardly from the bottom of said basin, a metallic lining for said basin having a tubular member fitting over said concrete project-ion and adapted to receive and support a lamp casing; and means arranged to drain said basin independently of the exterior surface off said column.

3. A stand of water permeable material, constructed and arranged to support a corrodible metal superstructure exposed to the Weather, and prevent staining the outer surface of said sta-nd with the products of cor rosion of said superstructure; comprising a column of cast concrete, having a catch basin at the top thereof; means, on said column,ar ranged to support said superstructure above said basin, in position to discharge Water from its surface into said basin, and a drain pipe extending from :said basin, doWnWardly insaid column and arranged to discharge exterior Yto said `column at the bottom thereof.

4. A stand of Water-permeable material, constructed and arranged to support a corrodible metal super-structure exposed to the weather, and prevent staining the outer surface lof said stand with the products of corrosion of said super-structure; comprising a column of cast concrete, having a catch basin at the top thereof; means, in said basin, exn tending in coaxial relation therewith, adapted to receive and support such super-structure, above vsaid basin, in position to discharge Water fromi its surface into said basin; and a drain pipe extending from said basin, downwardly in said column and 'l ranged to discharge exterior to said column.

5. A stand of Water-permeable material, constructed and arranged to support a corrodible metal lamp casing exposed to the weather, and prevent staining the louter surface of said stand with the products `of corrosion lof said casing; comprising a column of cast concrete, having a catch basin at the top thereof; means in said basin, adapted .to receive and detachably support a lamp Acasing, vabove said basin, in position :to discharge water from its surface into said basin, :and a drain pipe extending from` said basin, downwardly in said column, and arranged to discharge exteriorto said column.

In ktestimony whereof, I have hereunto signed my name at Philadelphia, `Pennsylvania, this seventh day offSeptember, 1926.
